1. What type of sentence is the following: "Wow, what a beautiful sunset!"
- A. Interrogative sentence
- B. Declarative sentence
- C. Exclamatory sentence
- D. Imperative sentence
Correct answer: C
Rationale: The sentence expresses an emotion ("Wow") and makes an exclamation, making it an exclamatory sentence.
2. Nuclear binding energy represents the energy required to:
- A. Separate an electron from its atom
- B. Separate protons and neutrons within a nucleus
- C. Cause nuclear fission
- D. Induce nuclear fusion
Correct answer: B
Rationale: Nuclear binding energy is the energy required to hold the protons and neutrons within a nucleus together. This energy is necessary to overcome the electrostatic repulsion between positively charged protons in the nucleus. Option A, separating an electron from its atom, is related to ionization energy, not nuclear binding energy. Option C, causing nuclear fission, involves splitting a heavy nucleus into smaller nuclei, releasing energy but not directly related to the binding energy. Option D, inducing nuclear fusion, involves combining two light nuclei to form a heavier nucleus, also not directly related to the energy required to hold protons and neutrons together within a nucleus.
3. What is the mass number of an element?
- A. The number of protons in an atom's nucleus.
- B. The number of neutrons in an atom's nucleus.
- C. The number of electrons in an atom's valence shell.
- D. The number of isotopes of an element.
Correct answer: B
Rationale: The mass number of an element is the total number of protons and neutrons in the nucleus of an atom. It is represented by the symbol A and is written as a superscript to the element's symbol. For example, the mass number of carbon-12 is 12, which means that a carbon-12 atom has 6 protons and 6 neutrons in its nucleus.
4. A car is traveling on a curved road. What force keeps the car moving along the curved path?
- A. Gravitational force
- B. Normal force from the road
- C. Air resistance
- D. Friction between the tires and the road
Correct answer: D
Rationale: In this case, static friction acts between the tires and the road, providing the centripetal force required to keep the car moving in a circle even though it's traveling in a straight line relative to the ground.
5. An element with atomic number 26 and mass number 56 is most likely to be:
- A. Iron (Fe)
- B. Cobalt (Co)
- C. Nickel (Ni)
- D. Manganese (Mn)
Correct answer: A
Rationale: Iron (Fe) - Fe-56 has 26 protons and aligns with the given atomic number and mass number.
6. he adrenal cortex produces a group of steroid hormones called corticosteroids. What is a MAJOR function of corticosteroids?
- A. Regulate insulin sensitivity and blood sugar levels
- B. Control blood pressure and electrolyte balance
- C. Stimulate the immune system and inflammatory response
- D. Promote growth and development during puberty
Correct answer: B
Rationale: The correct answer is B: 'Control blood pressure and electrolyte balance.' Corticosteroids, produced by the adrenal cortex, play a major role in regulating blood pressure and electrolyte balance in the body. These hormones, such as aldosterone, act on the kidneys to control the reabsorption of sodium and water, which in turn affects blood pressure and electrolyte levels. While corticosteroids can have effects on other physiological processes, their primary function is to regulate blood pressure and electrolyte balance, making option B the most appropriate choice in this context.
